Abstract
The utility model relates to gas purification, in particular to an air filter with high efficiency, high quality, and convenience in oil discharge, pollution discharge and attachment elimination through back blowing. The air filter comprises a cylindrical barrel body with a gas inlet, a gas outlet and a pollution discharge exit, and a gas purification chamber, a primary filter and a fine filter are sequentially arranged inside the barrel body from top to bottom. The air filter is characterized in that the gas inlet is connected with the gas purification chamber by a back blowing pipe, the bottoms of the barrel body, the primary filter and the fine filter incline towards the pollution discharge exit, an oil discharge pipe is arranged at one side of the pollution discharge exit and inside the barrel body, oil dirt can be discharged into the oil discharge pipe by virtue of gravity due to the inclining structure, the primary filter is of a honeycombed shape, and gas passes through honeycomb holes to enter the fine filter.
Description
Technical field
The utility model relates to purification for gas, particularly a kind of air cleaner.
Background technology
At present, existing air cleaner is very extensive in industrial application, mostly adopt multistage filtering, general using inertia interception, electrostatic interaction, and the means purifying air such as chemical filtering, the air inlet of equipment is generally located at cylindrical shell middle part, gas enters cylindrical shell, through primary filter, then through fine filter, finally from exhaust outlet, discharge pure gas.During work, dust is blocked by modes such as shock, static, often by air inlet, is blown afloat again, to work, brings very large inconvenience; Longevity of service, dust, ink etc., attached amassing on screen pack, has increased work difficulty, has reduced the efficiency of work.
Summary of the invention
The purpose of this utility model is exactly to solve above-mentioned technical problem, and a kind of high efficiency, high-quality are provided, and convenient for oil drainage blowdown, facilitates blowback to remove the air cleaner of attachment.
Technical problem of the present utility model is mainly solved by following technical proposals:
A kind of air cleaner, comprise cylindrical cylindrical shell, its cylindrical shell is provided with air inlet, gas outlet and sewage draining exit, described inner barrel is also provided with air-purifying chamber, primary filter and fine filter up and down successively, it is characterized in that: described air inlet also connects air-purifying chamber by blowback pipe, described cylindrical shell, primary filter and fine filter three bottom all tilt towards sewage draining exit direction, and described inner barrel sewage draining exit one side is provided with oil exit pipe.Incline structure utilizes gravity that greasy dirt is entered to oil exit pipe.Described primary filter is being cellular, and gas enters fine filter again through honeycomb hole.
Further, described oil exit pipe is provided with open sump oil import, and described fine filter is provided with oil drain out, and oil drain out is included in described sump oil import.Sump oil infiltrate fine filter, also can along inclined direction flow into the sump oil import of opening.
Further, described primary filter below is provided with screen pack, between screen pack and primary filter, has space.Can make the dust in primary filter drop out screen pack, then flow into sewage draining exit.Described screen pack adopts fibrous filter net.
Further, described screen pack side is one and is greater than 90 ° of angles, by cylinder inboard wall and bottom, fixes.
Concrete, described air inlet is provided with intake valve, and described blowback pipe is provided with blowback valve.
As preferably, described inner barrel is provided with pressure differential control device, when attachment is too many on filter, produces pressure differential, closes intake valve and gas outlet, opens blowback valve and blowoff valve inner barrel is cleaned.
The beneficial effects of the utility model are: simple in structure, with low cost, promote easily; Secondly, be provided with auto back blowing apparatus, conveniently inner barrel blowback cleaned; Last two-stage filter and screen pack and cylinder body bottom are all incline structure, and dust and greasy dirt drop on bottom position and unexpectedly again blown afloat, and have increased air inlet area, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. cylindrical shell; 2. primary filter; 3. fine filter; 31. oil drain outs; 4. air inlet; 41. intake valves; 5. gas outlet; 6. sewage draining exit; 61. blowoff valves; 7. blowback pipe; 71. blowback valves; 8. oil exit pipe; 81. sump oil imports; 9. air-purifying chamber; 10. screen pack.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings 1, the technical solution of the utility model is described in further detail.
Embodiment: a kind of air cleaner, comprise cylindrical cylindrical shell 1, its cylindrical shell 1 is provided with air inlet 4, gas outlet 5 and sewage draining exit 6, described cylindrical shell 1 inside is also provided with air-purifying chamber 9, primary filter 2 and fine filter 3 up and down successively, described air inlet 4 also connects air-purifying chamber 9 by blowback pipe 7, described cylindrical shell 1, primary filter 2 and fine filter 3 three bottoms all tilt towards sewage draining exit 6 directions, and inner sewage draining exit 6 one sides of described cylindrical shell 1 are provided with oil exit pipe 8.Incline structure utilizes gravity that greasy dirt is entered to oil exit pipe 8.Described primary filter 2 is put in example and is cellular in this reality, and gas enters fine filter 3 again through honeycomb hole.
Further, described oil exit pipe 8 is provided with open sump oil import 81, and described fine filter 3 is provided with oil drain out 31, and oil drain out 31 is included in described sump oil import 81.Sump oil infiltrate fine filter 3, also can along inclined direction flow into the sump oil import 81 of opening.Further, described primary filter 2 belows are provided with screen pack 10, between screen pack 10 and primary filter 2, have space.Can make the dust in primary filter 2 drop out screen pack 10, then flow into sewage draining exit 6.The present embodiment, screen pack 10 adopts fibrous filter net.Described screen pack 10 sides are one and are greater than 90 ° of angles, by cylindrical shell 1 inwall and bottom, fix, and can weld and can be bolted.Concrete, described air inlet 4 is provided with intake valve 41, and described blowback pipe 7 is provided with blowback valve 71.
Described cylindrical shell 1 inside is provided with pressure differential control device (not shown), when attachment is too many on filter, produces pressure differential, automatically closes intake valve 41 and gas outlet 5, opens 61 pairs of cylindrical shell 1 internal washings of blowback valve 71 and blowoff valve.
The present embodiment is the embodiment of the utility model example; for those skilled in the art; the utility model discloses on the basis of application process and principle; be easy to make various types of improvement or distortion; and be not limited only to the described structure of the above-mentioned specific embodiment of the utility model; therefore previously described mode is preferred version; and do not there is restrictive meaning; every equivalence of doing according to the utility model changes and revises, all in the scope protection domain of the utility model claims.
